I have defined 2 views for my document, Preview and Tree.
named the files :
...\Views\Document.Tree.xaml ->x:Class=[namespace].Views.Document.Tree
and
...\Views\Document.Preview.xaml ->x:Class=[namespace].Views.Document.Preview

result:
Caliburn can't find view for the document view model, did I get the naming convention wrong somehow?
also I intercept the LocateForModel func and added some logging, I expected the third param (of type object) to be the given context but it's always null.
I'm probably missing something obvious here ...
